Connecting the world with color

Raspberry Pi Bluetooth Gateway for Playbulb and CheerLights

Colin Kraft bought a Playbulb Candle and wanted the lights to show the latest CheerLights color. Playbulb uses Bluetooth to set its glowing color. There is a bundled app for iOS and Android that lets you set the color, effects, and intensity.

Colin had the idea to use a Raspberry Pi as a Bluetooth gateway. Since the Raspberry Pi is connected to your network and supports Bluetooth, the Raspberry Pi can check the CheerLights color and send it to the Playbulb using Bluetooth just like an app on your phone.

Details on how to use the Playbulb Candle with the Raspberry Pi and CheerLights are available on Colin’s blog.
